A high-velocity axial fan provides a strong, chilled airflow of 3,100 CFM into your space, delivering up to 30 degrees F of cooling. It only costs $0.03 per hour to operate this air cooler thanks to the incredible power efficiency. A set of caster wheels makes it easy to maneuver and position exactly where you want it, and a tray on the top keeps tools, water bottles, safety supplies, and more within easy reach.
Refurbished Evaporative Cooler
This is a manufacturer-refurbished Hessaire evaporative air cooler. It may have minor cosmetic damage, but it is backed by a one-year warranty.
Two Water Fill Options
-
Continuous Water Fill: Connect a garden hose to the float adapter during assembly to take advantage of the continuous fill option, eliminating the need for manual refilling.
-
Manual Water Fill: A spring-loaded front-fill door accesses the water tank for manual filling.Β
-
Cooling Media: Three hi-density XeL50 rigid media pads cool areas faster by allowing more air intake than the single panel in other swamp coolers.
-
Water Tank: The water reservoir holds 10.3 gallons, providing up to three to four hours of continuous cooling airflow. A level indicator at the front shows how full the tank is at a quick glance.
-
Oscillation: Turn on the air swing delivery system to evenly distribute the cool air in a wide, left-to-right coverage.
-
Speed Controls: Choose from three speed options or turn the fan-only mode on to circulate air in a stuffy room.
-
Casters: Four heavy-duty casters are included for installation and are stored inside the unit for easy transportation.
What our Experts Think
-
Industrial-grade cooling power β Delivers 11,000 CFM airflow, moving massive volumes of cool moisture across up to ~3,000 sq ft, perfect for large garages, warehouses, run-off events, barns, and commercial spaces.
-
Exceptional value with refurbishment β Factory-refurbished unit backed by a one-year limited warranty, offering like-new performance at a lower cost than a new MC92V model.
-
User-friendly & versatile β Dual water fill options (manual or continuous hose hookup), easy dials for fan speed/pump/oscillation, and adjustable louvers help tailor airflow and cooling where you need it.
-
Built-for rugged use β Large 32.8 gallon water reservoir, heavy-duty pads, oscillating design, and caster wheels support long runtime, broad coverage, and easy mobility.
-
Energy-efficient operation β Runs on modest power (β460 W) with low operating costs (~$0.05/hour), balancing high flow with economical performance.
-
Best in dry climates β As with all evaporative coolers, peak performance occurs in low-humidity environments; in humid regions, cooling feels less effective and adds moisture to the air.
-
Ideal for demanding spaces β Experts highlight its strength for industrial, commercial, and large open spaces where standard fans or small coolers canβt compete.
